Patent number: 11894078Abstract: Methods, systems, and devices for accessing a multi-level memory cell are described. The memory device may perform a read operation that includes pre-read portion and a read portion to access the multi-level memory cell. During the pre-read portion, the memory device may apply a plurality of voltages to a plurality of memory cells to identify a likely distribution of memory cells storing a first logic state. During the read portion, the memory device may apply a first read voltage to a memory cell based on performing the pre-read portion. The memory device may apply a second read voltage to the memory cell during the read portion that is based on the first read voltage. The memory device may determine the logic state stored by the memory cell based on applying the first read voltage and the second read voltage.Type: GrantFiled: May 26, 2022Date of Patent: February 6, 2024Assignee: Micron Technology, Inc.Inventors: Karthik Sarpatwari, Xuan-Anh Tran, Jessica Chen, Jason A.

Patent number: 10422498Abstract: A lighting assembly that includes an LED source that generates a light cone (solid angle); and a transparent near field lens having a front surface, a collimating surface, and an aspherical groove. The collimating surface collimates the light cone into a beam that reflects off of the front surface toward the aspherical groove, and the aspherical groove directs the beam away from the lens as an exit cone from a virtual focal point, positive virtual focal ring or a negative virtual focal ring. The exit cone may be evenly distributed, substantially forward or substantially rearward from the virtual focal point or virtual focal ring. Parabolic or aparabolic reflectors can be employed with lighting assemblies having a virtual focal point or virtual focal ring, respectively, to reflect the exit cone in a vehicular exterior lighting pattern.Type: GrantFiled: September 5, 2018Date of Patent: September 24, 2019Assignee: Ford Global Technologies, LLCInventor: Jason Durand

Publication number: 20070004550Abstract: A rotary recliner includes an outer rotary member having a first series of gear teeth on an inner circumferential surface thereof and an inner rotary member having a second series of gear teeth on an outer surface thereof. An eccentric is mounted to the inner rotary member and biases the second gear teeth into meshed engagement with the first gear teeth at a first position along the inner circumferential surface such that a clearance is created between the first gear teeth and the second gear teeth at a position on the inner rotary member opposite from the first position. A wedge carrier includes a pair of wedges extending from a body. The wedges are joined by a bridge portion with each wedge including a ramped surface that engages and applies a radial force on the eccentric to prevent relative movement between the inner and outer rotary members.Type: ApplicationFiled: June 30, 2005Publication date: January 4, 2007Inventors: Dagoberto Krambeck, Jason Durand
